Tetradecyl Thioacetic Acid

Technically an Omega-3 fatty acid, TTA is a non-metabolizable fatty acid that cannot be used for energy and may be able to burn fat via mechanisms similar to Conjugated Linoleic Acid. Lacking studies in humans at the moment, TTA appears to be a promising future candidate for fat loss and health.

Summary of Tetradecyl Thioacetic Acid

Primary information, health benefits, side effects, usage, and other important details

Tetradecyl Thioacetic Acid, otherwise known as TTA, is what is known as a PPAR-alpha activator. It is actually an omega-3 fatty acid, but has a sulfur group at the omega-3 position; because of this addition it cannot be burnt for energy and thus has no relevant caloric value to humans.

PPARa activation can be seen as protecting the body from excess fats (similar to PPARy activation). PPARa tends to clear fats from the blood into muscle or liver cells, and encourage them to be burnt for energy in these locations (by comparison, PPARy makes new fat cells for fats to reside in which minimizes their potential toxicity).

The clearing of fat from the blood causes a drop in lipoproteins and a lowering of LDL cholesterol, and the burning of fats causes either fat burning or reduced fat gain. TTA can also decrease blood pressure and exert an anti-oxidant effect, the four mechanisms making it a cardioprotective compound.

It is commonly used with the appetite suppressant oleoylethanolamide as a fat-burning combination.

How to Take

Recommended dosage, active amounts, other details

Not much evidence currently exists in human, but the standard dose appears to be 1g of TTA daily taken in divided dosages with meals.

Human Effect Matrix

Unlocked for Examine members

The Human Effect Matrix summarizes human studies to tell you what effects Tetradecyl Thioacetic Acid has on your body, how much evidence there is, and how strong these effects are.

Full details are available to Examine members.
Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The more evidence, the more we can trust the results.
Outcome Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
